Fast Beam Selection in Wireless Communication

17. The scheduling entity of claim 16, wherein the processor and the memory are further configured to receive at least one of a negative acknowledgment (NACK) of the DL data or a plurality of reference signals, from the beam sweep pattern configured to facilitate beam selection for a retransmission of the DL data.

20. The scheduling entity of claim 19, wherein the processor and the memory are further configured to transmit a downlink control information (DCI) or MAC control element (MAC-CE) to activate the beam sweep pattern.

21. The scheduling entity of claim 19, wherein the processor and the memory are further configured to transmit a radio resource control (RRC) configuration including the indicator configured to enable the semi-persistent scheduling of the beam sweep pattern.

22. The scheduling entity of claim 19, wherein the processor and the memory are further configured to transmit the indicator in an individual transmission that is temporally separated from the beam sweep pattern.

25. The UE of claim 24, wherein the processor and the memory are further configured to transmit at least one of a negative acknowledgment (NACK) of the DL data or a plurality of reference signals, in the beam sweep pattern.

27. The UE of claim 26, wherein the processor and the memory are further configured to receive a downlink control information (DCI) or a medium access control (MAC) control element, to activate the beam sweep pattern.

28. The UE of claim 26, wherein the processor and the memory are further configured to receive a radio resource control (RRC) configuration including the indicator configured to enable the semi-persistent scheduling of the beam sweep pattern.

29. The UE of claim 26, wherein the processor and the memory are further configured to receive the indicator in an individual transmission that is temporally separated from the beam sweep pattern.
